Born Kevin Sydney, he was a member of the X-Men and a close friend of Wolverine who was apparently killed in the second episode by Sentinels. He reappeared as a recurring villain in the second season where it was revealed that Mr. Sinister had saved and brainwashed him. Until the end of the season, through constant assurance from his teammates, Morph helped battle Sinister. Professor X finally removed his implants, but he needed much more rehabilitation. Morph later appeared in the episode "Courage", and in the series finale, "Graduation Day," where he briefly appeared as Professor X, while the professor was sick and dying due to an illness. He appeared to have more of his past snickering humor, probably suggesting that he was now mentally healthy and back on the team, this time permanently.
